| Abstract: | Objective:To explore the importance of 3 D reconstruction technology in cell microstructure research. Methods:Hela cells were collected, the sample was processed by OTO method for serial sections, and the back scattering electronic signals on the sequence sections’ were collected by the scanning electron microscope. The picture collection is aligned, segmented and the 3 D reconstruction was performed with Amira software. Results:The three-dimensional reconstruction of the cell was obtained, the mitochondrial length, width and thickness were measured and counted, and the three-dimensional structure of the mitochondria-associated endoplasmic reticulum membranes was observed. Conclusion:The 3 D visualization can show ultra-microstructure comprehensively and objectively compared to that in two-dimensional image, and the Serial Section 3 D reconstruction technology is of great significance in the study of 3 D visualization. |
